DuetWiFi Issues

Vignesh

I am new to the DuetWiFi board. I am using :

Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.19.2 (2017-09-01)
WiFi Server Version: 1.19.2
Web Interface Version: 1.19.

I followed the instructions on the website. I use a CoreXY configuration for the 3D printer. I have the following issues:

1. When I home the printer it homes fine, after it finishes homing it says "Homing Failed". I get the same error on Pronterface and DuetWeb Control. I am not sure why this happens.

2. I am not using any heated bed, but it shows it is at 2000 degrees. How can I remove it or make it 0?

Thanks

Regarding #1, please share your homing files. After homing, what colours are the homing buttons in DWC?

Regarding #2, use M140 H-1 in config.g to specify that there is no bed heater.

Vignesh

Thanks, M140 H-1 disable the bed temperature.

The buttons stay in yellow colour after homing.

My homing files is:```
[[language]]G91 ; relative mode

G1 Z10 F300 ; raise extruder nozzle

G1 S1 X-240 Y-240 F3000 ; course home X or Y

G1 S1 X-240 ; course home X

G1 S1 Y-240 ; course home Y

G1 X4 Y4 F600 ; move away from the endstops

G1 S1 X-10 ; fine home X

G1 S1 Y-10 ; fine home Y

M84

G1 Z150 F200 S1 ; course home Z
G1 Z-4 F100 ; move away from endstops
G1 Z10 S1 ; fine home Z

G90 ; back to absolute mode

G1 Z10 F300 ; send to (0,0,10)
G1 Z0 F200 ; send to (0,0,0)

M84

The problem is the M84 commands. They disable the stepper motors, so the firmware assumes that the motor position is no longer stable. So remove them. The motor currents will be reduced to the idle percentage automatically after the idle timeout.

Vignesh

Thanks, removing M84 fixed the issue.

I have one last issue, the command M114 does not give any output in Pronterface but works in DWC. Do you know why this happens? is there a fix for that?

dc42

Pronterface is very picky about the response format it expects, and it chokes on an extra space character in the M114 response returned by RRF. This space character is removed in RRF 1.20beta2. BUT that version has a bug in the code for homing CoreXY printers, so please wait for the next beta release.

Vignesh

okay, thanks. Can I use the same drivers you have in the github link for MAC computers too, or do you have specific drivers for MAC?

dc42

I don't think you need any drivers for Mac, same as for Linux.

Vignesh

okay, thanks!
